Hi Folks,
Regarding Attack, I would also like to add it can have a nasty
effect on some stones. Turquoise and many related stones are
often stabilized through the introduction of an epoxy-like
resin. This is also acted upon by the Attack. Especially if
you are removing stones from a southwestern style inlay, be
certain of the quality of the material.
